CHANGELOG.md

+# 4.0.4
+
+- Remove debug printing when parsing CSI sequences
+- Support NO\_COLOR environment variable
+
+# 4.0.3
+
+Remove unused code and update dependencies.
+
+# 4.0.2
+
+Fixes an error check in Ctrl-Arrow code, no difference in behavior. Cleaned up examples.
+
+# 4.0.1
+
+Fixes a regression in function keys F5 and above.
+
+# 4.0.0
+
+4.0.0 adds support for horizontal scrolling when working with `MouseTerminal`.
+
+## 3.0.0 to 4.0.0 guide
+
+A change is only necessary if you were matching on all variants of the `MouseEvent` enum without a wildcard.
+In this case, you need to either handle the two new variants, `MouseLeft` and `MouseRight`, or add a wildcard.
+
+# 3.0.0
+
+v3 release improves `raw` terminal API and enables support of any TTY target.
+
+## 2.0.0 to 3.0.0 guide
+
+Changes are only required if you were using `IntoRawMode` on generic terminals `W: Write`. Now, terminal
+is also required to implement [`AsFd` trait][AsFd-trait]. So replacing generic bounds with `W: Write + AsFd`
+should be sufficient.

 # 1.0.0
 
 Termion 1.0.0 is out! This release is breaking, which is also the reason for the semver bump.
